Abstract

The present invention relates to a drainage pump for a clothes treatment device, which is characterized in that it comprises: a housing for containing water; a first discharge port and a second discharge port protruding from the housing and being spaced apart from each other to form a movement path of the contained water; a water flow part is formed on the inner peripheral surface of the housing and has an impeller that forms the flow of the water so that the contained water passes through the first a discharge port, or discharge through the second discharge port; a drain pump chamber formed on an inner peripheral surface of the housing for receiving or storing the water before the water flows into the water flow part; And an inflow port is formed between the water flow part and the drain pump chamber so as to protrude toward the water flow part side.

Description

technical field [0001] The present invention relates to a drain pump. In particular, the present invention relates to a drain pump installed in a clothes treating device, and relates to a drain pump for a clothes treating device for draining or circulating water or washing water flowing in from a drum. Background technique [0002] The laundry treatment device is a device that puts clothes, bedding, etc. (hereinafter referred to as laundry) inside the drum and removes stains attached to the laundry, and performs processes such as washing, rinsing, dehydration, and drying. [0003] Based on the method of loading laundry into the drum, the laundry treatment apparatus is classified into a top loading method and a front loading method. Generally, a washing machine of a front loading system is called a front-loading washing machine. [0004] figure 1 Shows the appearance of a drum washing machine, figure 2 show figure 1 The interior of the front-loading washing machine. [...
